Color–color diagrams for new high proper motion candidates (μ/σ
μ > 5) detected with multi-epoch astrometry from
WISE. In each diagram, the colors in the group near the origin are consistent with those of main-sequence stars and brown dwarfs;
all of these candidates have detections in 2MASS that confirm their large motions. Most of the objects in the redder group
are probably galaxies or evolved stars; none have motions confirmed by 2MASS. For reference, the left diagram includes the
colors produced by fits to absolute magnitudes of L and T dwarfs (solid and dashed curves, Dupuy & Liu 2012) and a boundary
below which Kirkpatrick et al. (2011) selected candidate T and Y dwarfs (solid line). The candidate that is between the two
groups in the right diagram is the binary brown dwarf WISE 1049−5319 (Luhman 2013).
